Command line RDF/N3 tool
        
 <command> <options> <steps> [--with <more args> ]

options:
 
--pipe        Don't store, just pipe out *

steps, in order left to right:

--rdf         Input & Output ** in RDF/XML insead of n3 from now on
--n3          Input & Output in N3 from now on. (Default)
--rdf=flags   Input & Output ** in RDF and set given RDF flags
--n3=flags    Input & Output in N3 and set N3 flags
--ntriples    Input & Output in NTriples (equiv --n3=usbpartane -bySubject -quiet)
--language=x  Input & Output in "x" (rdf, n3, etc)  --rdf same as: --language=rdf
--languageOptions=y     --n3=sp same as:  --language=n3 --languageOptions=sp
--ugly        Store input and regurgitate, data only, fastest *
--bySubject   Store input and regurgitate in subject order *
--no          No output *
              (default is to store and pretty print with anonymous nodes) *
--base=<uri>  Set the base URI. Input or output is done as though theis were the document URI.
--closure=flags  Control automatic lookup of identifiers (see below)
<uri>         Load document. URI may be relative to current directory.

--apply=foo   Read rules from foo, apply to store, adding conclusions to store
--patch=foo   Read patches from foo, applying insertions and deletions to store
--filter=foo  Read rules from foo, apply to store, REPLACING store with conclusions
--query=foo   Read a N3QL query from foo, apply it to the store, and replace the store with its conclusions
--sparql=foo   Read a SPARQL query from foo, apply it to the store, and replace the store with its conclusions
--rules       Apply rules in store to store, adding conclusions to store
--think       as -rules but continue until no more rule matches (or forever!)
--engine=otter use otter (in your $PATH) instead of llyn for linking, etc
--why         Replace the store with an explanation of its contents
--why=u       proof tries to be shorter
--mode=flags  Set modus operandi for inference (see below)
--reify       Replace the statements in the store with statements describing them.
--dereify     Undo the effects of --reify
--flatten     Reify only nested subexpressions (not top level) so that no {} remain.
--unflatten   Undo the effects of --flatten
--think=foo   as -apply=foo but continue until no more rule matches (or forever!)
--purge       Remove from store any triple involving anything in class log:Chaff
--data              Remove all except plain RDF triples (formulae, forAll, etc)
--strings     Dump :s to stdout ordered by :k whereever { :k log:outputString :s }
--crypto      Enable processing of crypto builtin functions. Requires python crypto.
--help        print this message
--revision    print CVS revision numbers of major modules
--chatty=50   Verbose debugging output of questionable use, range 0-99
--sparqlServer instead of outputting, start a SPARQL server on port 8000 of the store
--sparqlResults        After sparql query, print in sparqlResults format instead of rdf

finally:

--with        Pass any further arguments to the N3 store as os:argv values
 

            * mutually exclusive
            ** doesn't work for complex cases :-/
Examples:
  cwm --rdf foo.rdf --n3 --pipe     Convert from rdf/xml to rdf/n3
  cwm foo.n3 bar.n3 --think         Combine data and find all deductions
  cwm foo.n3 --flat --n3=spart

Mode flags affect inference extedning to the web:
 r   Needed to enable any remote stuff.
 a   When reading schema, also load rules pointed to by schema (requires r, s)
 E   Errors loading schemas of definitive documents are ignored
 m   Schemas and definitive documents laoded are merged into the meta knowledge
     (otherwise they are consulted independently)
 s   Read the schema for any predicate in a query.
 u   Generate unique ids using a run-specific

Closure flags are set to cause the working formula to be automatically exapnded to
the closure under the operation of looking up:

 s   the subject of a statement added
 p   the predicate of a statement added
 o   the object of a statement added
 t   the object of an rdf:type statement added
 i   any owl:imports documents
 r   any doc:rules documents
 E   errors are ignored --- This is independant of --mode=E

 n   Normalize IRIs to URIs
 e   Smush together any nodes which are = (owl:sameAs)

See http://www.w3.org/2000/10/swap/doc/cwm  for more documentation.

Setting the environment variable CWM_RDFLIB to 1 maked Cwm use rdflib to parse
rdf/xml files. Note that this requires rdflib.

Flags for N3 output are as follows:-
        
a   Anonymous nodes should be output using the _: convention (p flag or not).
d   Don't use default namespace (empty prefix)
c   Comments added at top about version and base URI used.
e   escape literals --- use \u notation
g   Suppress => shothand for log:implies
i   Use identifiers from store - don't regen on output
l   List syntax suppression. Don't use (..)
n   No numeric syntax - use strings typed with ^^ syntax
p   Prefix suppression - don't use them, always URIs in <> instead of qnames.
r   Relative URI suppression. Always use absolute URIs.
s   Subject must be explicit for every statement. Don't use ";" shorthand.
t   "=" and "()" special syntax should be suppresed.
u   Use \u for unicode escaping in URIs instead of utf-8 %XX
v   Use  "this log:forAll" for @forAll, and "this log:forAll" for "@forSome".
/   If namespace has no # in it, assume it ends at the last slash if outputting.

Flags for N3 input:

B   Turn any blank node into a existentially qualified explicitly named node.


Flags to control RDF/XML output (after --rdf=) areas follows:
        
b  - Don't use nodeIDs for Bnodes
c  - Don't use elements as class names
d  - Default namespace supressed.
l  - Don't use RDF collection syntax for lists
r  - Relative URI suppression. Always use absolute URIs.
z  - Allow relative URIs for namespaces



    Flags to control RDF/XML INPUT (after --rdf=) follow:
        S  - Strict spec. Unknown parse type treated as Literal instead of error.
        T  - take foreign XML as transparent and parse any RDF in it
             (default it is to ignore unless rdf:RDF at top level)
        L  - If non-rdf attributes have no namespace prefix, assume in local <#> namespace
        D  - Assume default namespace decalred as local document is assume xmlns=""
        R  -  Do not require an outer <rdf:RDF>, treating the file as RDF content (opposite of T)

    Note: The parser (sax2rdf) does not support reification, bagIds, or parseType=Literal.
          It does support the rest of RDF inc. datatypes, xml:lang, and nodeIds.
